Process scheduling apparatus, process scheduling method, program for process scheduling, and storage medium recording a program for process scheduling

摘要

A process scheduling apparatus has a delayed task handling process for processing delayed tasks having variable priorities and multiple other processes for handling processes other than delayed tasks. Fixed priorities are assigned to the other processes. The process scheduler sequentially executes the delayed task handling process and the other processes according the assigned priorities. A delayed task registration processor stores newly generated delayed tasks with assigned priorities in a queuing table. A delayed task priority controller selects the delayed task with the highest priority in the queuing table. A process priority controller sets the priority of the delayed task handling process to the same priority as the priority of the delayed task with the highest priority.
